Subnetting is a networking technique that divides a larger IP network into smaller, logical sub-networks (subnets) to improve routing efficiency, security, and address management. Network engineers and IT administrators use subnetting, often expressed via CIDR notation, to allocate IP addresses efficiently and isolate traffic between departments or devices. It's a core skill tested in networking certifications like CompTIA Network+ and Cisco's CCNA.
